We live in a digital world. Just look at where you’re reading this article right now—without that phone, tablet, or laptop in front of you, this content would never reach you.

Now, I’ll be honest and say that I’m old-fashioned, which is why I prefer using Post-its instead of Apple Calendars, holding a physical book rather than reading with a Kindle, or talking in person rather than through social media. But like everyone else, I’ve had to adapt to life’s changes—and quite honestly, it’s actually made me a lot more productive and efficient in everything I do.

So, while none of the skills below are completely necessary to survive and thrive in this world, they might be pretty useful to pick up in your free time. If nothing else, understanding what other teams in your office do will help you communicate more clearly with them when you’re collaborating on projects.

The best way to learn anything nowadays? Online classes—they’re cheap (or completely free), and you can take them anytime, anywhere, and in any fashion you prefer. See, the future isn’t so bad after all.
